Pre-XRCF Calibration Review - Presentation Overview (10/15/96)

           AXAF Grating Spectrometers
                                                            
- Response function of integrated system - overview
    Calibration Product(s) for AXAF Grating Spectrometers
      effective area vs. E (full vs "core" effective area, cross-disp effects)
      LSF vs E (centroid, FWHM, core gaussian, outer core, wings, )
      (and/or combined into one response function matrix)
    Science drivers and required calibration accuracies

- Physical models of key sub components
   HRMA (P1H1 P3H3 P4H4 P6H6)
   HETG (shells 1,3,4,6)
   LETG (uniform?!)
   ACIS-S, HRC-S, HRC-I, ACIS-I
     (CCDs, MCPs, UV/ion, opt block filters, Drake flat)

  For each physical model above summarize: 
   Basis for model
   Model Creation and Testing
   Uncertainties (pre XRCF)
   Unconstrained (even) after XRCF

- Model Details for HETG, LETG
  HETG
   Synchrotron results, compare with model and X-GEF
   Likely error on X-GEF measurements
   Range of grating parameters for shells 1,3,4,6
   Subassembly prediction, modeling it
  LETG
   Subassembly IR/Diffractometer data
   Range of LEG parameters
   Subassembly prediction, modeling it
  Efficiency Model composed of many gratings
    (and for HETG different mirror shells)
   Can be fit with a several-grating model?
   Adjusting model to match data

- Model Details for Drake Flat(1.6Mb .ps)
   ...

- Pre-XRCF Calibration Status
   Plots of "products" and their errors if only subassembly data are used

- XRCF Testing
   Summary of identified calibration priorities
   Test list summary
     .exp file written to clearly indicate purpose of measurements
     MARX simulations (most), SAOSAC simulations (as needed)
     Phase 1  HXDS
     Phase 2a HRC-I, HRC-S, ACIS-2C
     Phase 2b HRC-I, HRC-S, flight ACIS
   Measurement priorities for Grating Calibration Measurements
   Model constraints that these measurements will provide
   Assummed calibrations (XSS,HXDS,HRMA,FPSIs,...)

- XRCF (Simulation and) Analysis
   "Bending" model(s) to measured data
   ASC s/w (pipelines, interactive tools/environment)
   MST 3rd floor s/w, Cambridge s/w
   HRC 3rd floor s/w and environment
   ACIS 3rd floor s/w and environment
   XRCF Data Analysis plan (Tasks, who, dates: prelim, final)
